jQuery Drop事件未触发

Question

I'm trying to move links (.link) from one div (.folder) to another but the drop event is not firing. I think I made all .link divs droppable areas by preventing default behaviour in dragenter and dragover events. Here's the code:

$(document).ready(function() {
    //Logic for create folder button
    $("#create-folder-button").click(createFolder);

    // //Logic for drag and drop for the links
    $(".folder").on("dragstart", function(e) {
        console.log("dragstart");
    });
    $(".folder").on("dragenter dragover", function(e) {
        e.preventDefault();
    });
    $(".folder").on("drop", function(e) {
        e.preventDefault();
        console.log("drop");
    });
});

The "dragstart" prints but the "drop" doesnt.

You need to use event.stopPropagation() :

$(".folder").on("drop", function(event) {
    event.preventDefault();  
    event.stopPropagation();
    alert("Dropped!");
});
